摘要: The multicomponent nonideal gas lattice Boltzmann model by Shan and Chen (S-C) can be used to simulate the immiscible fluid flow. In this paper, we show that the relaxation constant τ≤1 is a necessary condition for the immiscible fluid flow in the S-C model. In a system with very complex boundary geometry, for 0.8≤τ≤1, the S-C model describes the immiscible flow quite well, and τ=1 is the best.
